The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the engine's reading, and the reference the archive is measured against.

Peter's own rating

Rating
7
Peter's rating is his own eye, not the engine's, and he never gives a 10.

Older engine

V10C
9
From an earlier engine (V10C). Its scale differs from V23's, so it is only ever compared with other readings by the same engine.

How the number was made

Read by the Visual Analysis Engine, version 23.8, on 2026.10.06: measured by code, then read 5 times by Claude Opus 5.5 against three reference paintings (R1 to R3), each read independent of the others. How the engine works.

WHAT THE CODE SEES

Three views of one sheet.

Left, the photograph. Centre, the tone stretch the model is shown beside it: the darkest 45% of tones spread over the whole range, so flat black, banding and stains show. Right, every pixel as the measuring code classes it: cyan black ink, deep teal translucent grey, stone the palest ink, near black bare paper.

TONAL STEPS

4 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Life inside the black: 0.064 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 3 of 5 qualities.

Each quality placed on its ladder by each read, and the mean the engine keeps. Where reads differ, they differ by one rung; close calls resolve down.

READ 1, IN ITS OWN WORDS

“A radial burst in the same family as R3, with legible stacked passes. It is heavier and more crowded, with blunter slab wedges and darks in the lower half that read flatter.”

Form · BUILT

Radial wedge strokes hold their walls and follow the arc, but lower-right and left dark wedges read as squared, slab-like blocks with blunt ends.

WEAKEST Bulky dark rectangular wedges, lower right

STRONGEST Upper-right radial fan strokes following the arc

Tonal depth · MODELLED

Stretched view shows banding and grain in most wedges (modulation 0.064, four steps), but the large lower-centre and lower-right darks read flat at viewing distance.

WEAKEST Dense lower-centre dark mass near-uniform in colour view

STRONGEST Upper-right fan with banded, stepped greys

Layering · ORDERED

Many translucent radial passes stacked in readable order; overlaps step tone outward across the sheet, though the lower-centre stack thickens toward opacity.

WEAKEST Lower centre where stacked darks merge

STRONGEST Overlapping translucent wedges in upper right

Composition · WORKING

Radial burst around a white centre gives clear direction, but 93% coverage crowds the frame; corners and lower half feel jammed and heavy.

WEAKEST Crowded, near-total coverage leaves little shaped paper

STRONGEST Central white circle anchoring the radial burst

Material and surface · SOUND

Ink controlled with streaked dry-brush edges; small specks top right and a cloudy grey patch at mid-left sit away from principal darks.

WEAKEST Cloudy pale wash at left edge

STRONGEST Dry-brush streaks in vertical lower-centre gap

FLAWS

3 distinct places, 0 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 3 distinct places, 10 mentions in all across 5 reads; the number in each ninth is how many times a flaw was named there. Reads agreeing on a place strengthen the evidence for one flaw; they do not multiply it.

GEOMETRY

Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 2 principal ink masses traced (cyan), 7 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 53% crisp, 47% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 7.3.

Engine v23.8, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on 24 randomly chosen paintings so the median sheet scores 5. The scale is relative to this archive, not to painting in general, and a difference of less than half a point between two paintings is noise.
